The uploaded movie saves almost half a second in tower 5 thanks to the new finding. When continuing to TAS the remaining towers, the uploaded movie file is at one point 33 frames ahead of the current TAS (due to favorable "random" lag). However, it falls behind during the transition to the bonus level of tower 7 ("random" lag) and never recovers, clocking in 3 frames after the current TAS.
It seems like it should be possible to (e.g.) play around with the screen transitions of the earlier towers to find a combination not resulting in the extremely laggy screen transition to the 7th bonus level. However, that is nothing I plan to do.
#638292604205474479 - Area 4 Room 3 conceptual solution
Conceptual solution of A4R3 that is faster than the currently published TAS. The movie is far from optimized, so better rat (and block?) management could likely save more time.

Movie originally created by Aqfaq in FCEU 0.98.15. The intention of the uploaded movie is to sync Aqfaq's movie on a modern emulator. The movie desyncs near the end of chapter 6 (a bit before Aqfaq's movie stopped).
47 frames of improvement over the current TAS (4838M). This was the result of a fairly quick test (without even using RAM-watch) and is probably possible to optimize further. The last three towers don't sync, but it's just a matter of lag, so would be trivial if anyone is interested.
